FAN-OPERATING- MEANS.

Application filled my 6,

To all whom it may concern:

Be it known that T, ANis A. BARooDY, a citizen of the United States, residing at Petersburg, in the county of Dinwiddie and State of Virginia, have invented certain new and useful Improvements in Fan-Operating Means, of which the following is a full, clear, and exact description.

The invention relates generally to fans and means for operating the same, and one of the objects of the invention is to provide an extremely simple construction .by which the fan may be instantly rendered operative or inoperative.

Another object of the invention resides in a new and improved means for adjustably and resiliently mounting the fan shaft.

Other and further objects and advantages of the invention will be apparent from the following detailed description, when taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevational view of the complete device.

Figure 2 is a vertical longitudinal sectional View of the complete apparatus.

Figure 3 is a vertical transverse sectional view taken on line 3-3 of Figure 2.

Figure 4: is a detail elevational view of a bracket for mounting the device on a. cash carrier or adjacent any! other desired operating means; and

Figure 5 is a horizontal sectional view taken on line 55 of Figure 2.

Referring to the drawings more in detail, numeral 1 indicates a pulley which is preferably a part of a cash carrier system. No

invent-ion resides in the cash carrier system itself, and it is, therefore, not deemed necessary to illustrate such a system; but in my pending application No. 591,298, filed September 29, 1922, I have illustrated a portion of such a system in combination with a fan, and reference may be had to that application for a more complete disclosure of the carrier system. While the pulley 1 preferably forms a part of a cash carrier system, it is to be clearly understood that it does not necessarily form a part of such a system and that the pulley may! represent any driving means for the fan.

Numeral 2 refers generally to a bracket which may be mounted on the frame of a cash carrier system, or in any other desired location. Secured to the top of the bracket 2 is a casing 3 in which is mounted for 1924. Serial No; 711,424.

sliding movement a rectangular shaped shaft holder 4. The shaft holder has a sliding movement, but it cannot rotate because it is rectangular in shape and cooperates with the vertical inner walls of the casing. Mounted for rotation in the shaft holder 4- is the fan shaft 5 carrying at one end the fan 6 and at the opposite end a soft rubber wheel 7. An adjustable collar 8 is mounted on the fan shaft to cooperate with the end of the shaft holder, and one or more grease cups 9 may be employed for lubricating the rotary shaft.

A lug 10 is formed on the bottom of the shaft holder, and a coil spring 11 has one end mounted on this lug and the other end mounted in a recess 12 formed in the base of the container. By this construction the shaft holder and rotary shaft are resiliently mounted and are normally held in an ele vated position. The upward movement of the shaft holder is limited and adjusted by means of the thumb screw 13.

The means by which the fan may be instantly thrown into or out of operative po sition will now be described.

A cam member 14 having an upwardly inclined surface 15 and a flat surface 16 at the top of the incline is pivotally mounted on the top of the shaft holder by means of a screw 17 or the like; and the cam menr her is provided with a finger 18. for oscillating said member to and from operative position. The adjustable set-screw 13 engages the upper surface of the cam member.

The operation is as follows:

Assume the parts are in the position illustrated in Figure 2 and in Figure 5 (full lines). With the cam positioned as illus trated the set-screw is engaged with the fiat upper portion of the cam, and hence the shaft holder and shaft are depressed, which causes the wheel 7 to frictionally engagethe grooved pulley 1, whereupon the fan is caused to rotate. Now when the cam member is rotated to the dotted line position (Figure 5), the inclined surface of the cam permits the shaft holder to move upwardly under the pressure of the spring 11, thereby releasing the wheel 7 from contact with the pulley 1 and stopping the rotation of the fan. Figure 3 clearly illustrates the position of the various parts when in inoperative position.

It is thus seen that the movement of the finger 18 throws the fan into operative or inoperative position; and that the upper and lower position of the shaft holder may be varied by the adjustment of the screw 13,

thereby providing means for taking care of the wear of wheel 7 and providing for adjustments to suit different installations, etc.

From the foregoing description it is apparent that the device is extremely simple in construction, and that it will function in a highly efficient manner. It will also be apparent that the device is particularly adapted for use in connection with a cash carrier system, although the invention is not limited to that particular use.

In accordance with the patent statutes, I have described what I now believe to be the best embodiment of the invention, but 1 do not wish to be understood thereby as limiting myself or the scope of the invention, as many changes and modifications maybe made without departing from. the spirit of the invention; all such I aim to include in the scopeof the appended claims.

Having fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. Fan operating means, including a vertically movable shaft'holder, a rotary. shaft mounted. in said holder, a fan mounted on one end of said shaft and a wheel mounted on the opposite end thereof, a spring normally pressing said holder upward, means for moving the holder downward against the pressure of the spring, and a driving pulley adapted tobe frictionally engaged by the wheel when the wheel is lowered.

2. Fan operating means,including a vertically movable shaft holder, a rotary shaft mounted in said holder, a fan and. wheel mounted on said shaft, and means for raising' and lowering the shaft holder, said means including a cam pivotally mounted on the: shaft holder. I

3. Fan operating means, including a movable shaft holder, a rotary shaft mounted in said holder, a fan and wheel mounted on the shaft, a spring exerting pressure on one shaft, a spring tending to move the holder in one direction, a cam pivotally mounted on the holder opposite to the spring, an outwardly projecting operating finger carried by the cam, and a lug engaging the face of the cam.

5. Fan operating means, including a movable shaft holder, a rotary shaft mounted in the shaft holder, a fan and wheel mounted on the shaft, a spring tending to move the holder in one direction, means mounted on the holder for moving it up and down, and a longitudinally adjustable lug engaging said means.

6. Fan operating. means, including-a movable shaft holder, a rotary shaft mountedin the shaft holder, a fan and wheel mounted on the shaft, a spring tending to move the holder in one direction, a cam pivotally mounted on the holder opposite to the spring, anda thumb screw engaging the face of said cam. I

7. Fanoperating: means, including a-movable shaft'holder, a rotary shaft mounted in the shaft holder, a fan and wheel mounted on the shaft, a springtending to move the holder in one direction, a cam formoving the holder in the opposite direction against the pressure of the spring, and adjustable means engaging said cam for varying the limits of movement of said holder.-
